This YouTube video explains how to build a major and minor chord on the piano, as well as some descriptors of the chords. It is easy to follow and visual, as well as not overly wordy.

This YouTube video is the song "Hello" in a major key, which could be used for demonstrating the impact of flipping the tonality of a piece of music. I chose it because it is a popular song and the tonality change impacts the feel greatly.

This website explains major and minor tonality in a clear way. I chose it because it contains short audio clips which take pieces of familiar music, such as Happy Birthday, and put them in major and minor keys in order to quickly compare. It also explains tonality well.

This image describes the intervals in a major and minor chord (or triad) in a clear, mathematical way. I like how it contains both major and minor, and how it uses the same chord to demonstrate the difference between major and minor.

This is an ear training game I made on musictheory.net. It is interactive and could be used either as a quiz among partners or a speed/accuracy race in a class. I appreciate how adaptable and easy this website is both for teachers and students to use to learn about music theory. This quiz could be used in small groups, individually, or as a class opener game.

This website explains major and minor tonality in more detail. It also explains major and minor scales. I thought it was a clear read with more information than some of the other resources. It could be used in teaching or for individual student reading.

This is another "Happy Sad Song" from The Gregory Brothers on YouTube. This video has a reference to Disney, which is relevant to the students, and it provides another nice comparison between major and minor keys in music.

This is the musictheory.net lesson on chords. I love the layout of this website. I love how the content is broken up into slide format, rather than put in large paragraph chunks of text. This clearly explains major and minor chords with both the staff and the keyboard. The only downside is that the teacher cannot limit the amount of information presented, so students may wander into Augmented or Diminished chords and get confused. Nevertheless, this is a great resource.

This website teaches about major and minor scales from the perspective of a guitar. It provides an alternative approach to an important topic. It also has images of the frets and audio demonstrations, which is interesting! This can help develop students' ear and expose them to instruments other than the piano.

This is an interesting article on the science of major=happy and minor=sad. It was written from a popular music perspective, but it can be applied to all music. It suggests that much of this correlation is cultural and that other influences affect our emotions as well, such as tempo. I think this could be a good read for students because it contains bands that the students can relate to, relevant YouTube links, and is an all-around interesting read on the subject.
